I have time but not enough.

I did not say it quite clear. 2 years ago I thought that foreign education for children was very simple so I did not pay too much attention to my son. At the time I was studying full time and did not care about his study that much. Now I regretted a lot about ignoring him at the moment. I realized this problem last year when I found he had problem in understanding text. He could read but he does not realy understand the meaning. This affects his learning about math as well. In general, now I study with him from 6:30 to 9:00, except 30 minutes for dinner. Still it is not enough. You may not imagine how slow can it be for him to learn. Any way I feel better now. I will look for external help as well.
